Early Data in E-Cigarette Study May Raise Safety Concerns

A laboratory study presented early this year reported that the nicotine-laced vapor generated by an electronic cigarette promoted the development of cancer in certain types of human cells much in the same way that tobacco smoke does. Researchers involved in the little-noticed study emphasized that their findings were preliminary and that the study [...] Read more

500 Million-Year-Old Embryos may Provide Key to Early Evolution

Researchers at the University of Missouri have discovered rare, fossilized embryos that may provide valuable insight into a time of rapid expansion and diversification among the world's first organisms, according to a release from the school. Known as the "Cambrian explosion," most of the world's marine invertebrates first appeared in the fossil [...] Read more

Scientists Detect A Particle That Could Be A New Form Of Matter

Physicists working at the Large Hadron Collider have spotted a long sought-after exotic particle that's the strongest evidence yet for a new form of matter called a tetraquark. Here's what the discovery could mean to astrophysics. You may have heard that CERN announced the discovery of a strange particle known as Z(4430). A paper summarizing the [...] Read more

Climate-changing microbes 'made 90% of species on earth extinct'

Climate-changing microbes may have caused the biggest mass extinction in history 252 million years ago, scientists believe. Volcanic eruptions had previously been blamed for the sudden loss of 90 per cent of all species on earth at the end of the Permian era. But new research suggests volcanoes played only a bit part in the catastrophe. The chief [...] Read more
